'Knowledge' in the Bible

Of the sons of Issachar, men who understood the times, with knowledge of what Israel should do, their chiefs were two hundred; and all their kinsmen were at their command.

What more may David say to you? for you have knowledge of your servant.

Only may the Lord give you wisdom, and knowledge of his orders for Israel, so that you may keep the law of the Lord your God.

“As for you, Solomon my son, know the God of your father [have personal knowledge of Him, be acquainted with, and understand Him; appreciate, heed, and cherish Him] and serve Him with a blameless heart and a willing mind; for the Lord searches all hearts and minds, and understands every intent and inclination of the thoughts. If you seek Him [inquiring for and of Him and requiring Him as your first and vital necessity] He will let you find Him; but if you abandon (turn away from) Him, He will reject you forever.
